My question is: What causes the pollution?, there are a lot of answers to this question, because there are plenty of factors that causes the pollution, so I'm going to name gthe principal ones. Firstly I need to defined the concept of pollution: is something that causes some sort of damage or problem to the enviornment or in the atmosphere. It can3 a substance or some kind of energy and is always something negative. The pollutants can be solid, liquid or gaseous and, obviously they doesn't have a natural origin, so usually they are generated by the human activity. Also, pollutants and society have a relative relation, due to the fact that when societies grow in quantities, the pollutants also grow and the pollution is worst and bigger. As I already said, the pollutants can be solid, liquid or gaseous. The pollutants that are in solid state, are generally composted by trash in all its possibly forms and they are the cause of land (floor) pollution, air pollution and water pollution. The liquid pollutants affect seas, lakes and oceans, so they cause the dead of a lot of animal species. And, the last ones are gaseous pollutants, that are caused by some gases that are released by some companies that uses petrol, or another substances that may be bad for the environment.
Another important cause of the pollution is that not everyone is conscious about what causes it and what are the consequences, so is very difficult to stop it. For example, many people doesn't care about recycling paper (for example), and this is very important because if we could reduce the consume of paper, we could reduce the destruction of many forests too. And also make that the companies that produce paper reduce their level of contamination.
Also, the air conditioners release a huge quantities of gases that contaminate a lot, but people isn't as conscious as they should be or don't care enough about the environment, so they use the air conditioners without limits and this makes the pollution even worst. Apart from this, there are some people that doesn't care about the trash they generate, so sometimes they leave papers or something on the streets, or in some parks, and this things usually have a long degeneration time, so there have to past a few years after they start to degenerate.
And is important to say that the pollutants can also provoke diseases in humans beens, like mutations, some kind of tumor and also respiratory diseases. So human race has to be conscious about their consume so we could at least try to make the pollution stop growing so the planet can have a better future.
In conclusion, societies are the mainly cause of the pollution, because of many of the reasons I already gave, like the gases some company releases or the trash we, as human beens, generate in our lives. And, there are different kinds of pollutants, like solid, liquid or gaseous and each one generates a different kind of pollution.
